Chapter 4, Dances with Dragons. The fate of the mutineers, from the books.

That means, possibly we will be seeing a new character arrive next week? But it still doesn't answer the question...did Jon Snow think of the mutineers as a security issue in the books? I don't remember it, if he did.

First? Locke. He's purely a creation of the show. I think he was originally intended to be a stand-in for Vargo Hoat, leader of the Brave Companions. He was at Harrenhal, and he cut off Jaime Lannister's hand in the book. But in the show they've folded his role into Locke who is one of House Bolton's men. And he made his way up to The Wall? Really? I understand Roose Bolton wanting to eliminate the last of the Starks in an effort to completely secure the North. I just don't recall Theon/Reek ever letting the real info about Bran and Rickon's true fate getting exposed to Ramsey Snow and thereby Roose Bolton.

The events north of The Wall are definitely a creation of the show. And you know that simply because none of those Night's Watch traitors were ever POV characters in the books. I thought that the fate of the traitors had been left as them having killed one another off over time. The sequence with Summer and Ghost was definitely a little surprising, and it left me hoping that the two dire wolves would be reunited. And then for Bran and company to get captured? Again, another divergence. But I think the showrunners are trying to build some of the suspense and danger as Bran, Meera, Jojen and Hodor make their way North.

But that last scene? OMG that was creepy. Again, a creation of the show since those characters were never established as POV characters.

Yes, I've had the same confusion brewing since last week's episode. This week, I was definitely trying to remember what was book and what was just show. Couldn't remember a Locke character...never remembered Summer and Ghost interacting. Finally settled on the same conclusion as you and decided I'd wiki it all later...none of these were POV characters. In fact, we're never explicitly told in the books what happens when the Others get Craster's babies. It's implied that they convert them, but we never really know.

What's still making it a little confusing, though, is that the showrunners make a very valid point...the mutineers at Craster's would have been a serious security threat to Castle Black. But I don't remember that ever being addressed by Jon Snow...only vaguely remember through Summer's POV that they were all dead. So is HBO addressing a plot hole? Jon should have realized in the books that the Craster survivors posed a threat.

Rosita's really just eye-candy at this point and barely spoke till this episode.

Indeed. Almost to the point of being annoying....it's one thing that every woman who survived to this point is a bit of a looker...it's TV. Fine. It's another thing altogether that Rosita is out there cosplaying a fanboy's Laura Croft.
